IMPROVEMENT IN- HAT-MACHINES.

The Schedule referred to in these Letters Patent and making parl: f the same.

To all whom it may concern -Be it known that I, OHAnLns M. OseooD,'of

Amherst', in the county of Hampshire and Stateot Massachusetts, have invented an Improvement in VlaIat-llachiues; and I do hereby declare the following to be a`fu1l, clear, and exact description, which will `:enable those skilled inthe art to make and, use the same, reference being had to the accompanying dran ing forming part ot' this specication, in which drawing- Figure l represents a vertical section of this invention, the liuc melig. 2, .indicating the plane of section. Y Figure 2 is a horizontal section vof the same taken vinthe plane indicated by the line y y, iig. l.4

Similarl letters indicatecorresponding parts.

i This inyention relates to a gauge for ascertaining the amountof material in the shells, so called, of hats Aprevious lto blocking and finishing them.

It consists in a table or platform, which contains a socket or cavity to receive the crown .and scales or graduated marks formed on the tableor platform, outside of `the socket or cavity; and of a plunger, which sers-es to force the crown down into'sa'd cavity, so that thc brim is either drawn in or forced out, according tothe quantity'of matcri l contained i.n the crown; and bythe scale on the ta le, the size to which 'thehat can be blocked will be ascertained with ease and facility.

The letter Al designates the .table or' platform,i

which is supported upon suitable standards B.

In about the center ofthe table I makean opening to receiveV a removable socket, C, et' metal or -any suitable hard material, which I make with a flange,

D, around. its edge, so that it can be supported Aupon the edge of the opening in the table.

The socket C is oval in shape in this example, but can be made of any-form that may he desired, and immediately above it' I suspend a plunger or die, E, Vof like shape, and which I also make-of metalor other "lhe plunger is fastened to the underside of a'sliding frame, Il, by nicans of ears or'iianges that project from thc upper edge of the plunger, and it can, like the socket 0, be removed in order tosubstitutc other sizes, or i'or repair, as may be dcsircd' The sliding frame F isv guided between 'standards H H, at the ends of thc table, 'and the tops of these standards are secured in a cross-bar, I, to the under side of which is fastened one end of a spiralspring, J, whose other end is secured to the sliding frame in such a mannert-hat the force of the spring is continually exerted to draw the Vframe'with The sliding frame F is connected, by vertical rods K K, to a treadle-bar, L, over which extends a treadle, M, which works on apivot arrangedon the lower part of the frame ot the table.

Upon the surface of the table A, I arrange a gradu- :ttcd scale, N, which commences at or nearthe socket G, and extends outward therefrom a sufficient4 distance to enable one to measure stock ofthe largest diameter.

In the present example I have made the scale upon metallic plates let into the surface of the table on each'side of the largest diameter of' thesockct C, the lines or" the scale being concentric witl'r-'thc adjacent edge of the socket or approximately. so; but the scale can be made upon all sides of the socket, `or confined to one side, as may be preferred, or, instead ot consisting of curved lines, the scale can be made by placing marks in radial lines that extend outward from the socket.` l

The scale is marked with iigures and fractions that denote' the measurement-of the diameter of the stock, orthe extent to which its edges extend upon the table. l

-In operating the machine, I place a 'shell upon the table, with the convex sideof its crown over the socket C, and then bring the plunger into it in such.

Vexcess is forced ont, and the brim extends further ont ou the Scale or if the crown contains a deficiency of material, the brim is drawn Vin on the scale, and the vcxactamount of material canthus be ascertained.`

Iidesired, the socket and thel plunger can be reversed without changing the result. The spring might be replaced by a weight.

What I claim as new, and desire to secure by Letters Patent, is

The 'graduated table A, in combination with the socket G and plunger or die E,'substautially as above described.
